Yes, that's a good point not to overfill. In this case, there is enough user's with experience to convince me that it is safe to fill to a point where I can visually see the fuel in the neck, but not so high as to cover the evap vent. Also having a bit of a drive after fillup to settle the fuel further down the neck is recommended as well. I end up having to fill every tank with the nozzle on about the second click in to keep the fuel from frothing up the neck and activating the nozzle stop. It will click and stop almost immediately apon starting a refuel on an empty tank even with taking care not to squeeze too fast of a flow. I've been trained pretty well on fueling quality and station loyalty with the diesel I had before. Poor fuel made a huge difference in my Jetta's mileage. The skyactive engines use piston and timing tech to run 87 octane and vary timing atkinson style to vary compression from 6-13:1 in USA.
